Installation
We recommend to thoroughly clean the garden pond to ensure almost maintenance-free operation of the
FiltoMatic CWS from the very beginning. OASE's recommendation for this cleaning work is the use of the
pond sludge suction unit Pondovac. In general, cleaning work can be omitted when the FiltoMatic CWS is
used in a newly installed garden pond.

P
lan the installation of the FiltoMatic CWS. Careful planning and taking the environmental conditions into
account will lead to optimum operating conditions for the FiltoMatic CWS.
The following points can help
you with your planning.
► A water course guarantees optimum water return from the FiltoMatic CWS to the garden pond. In this
manner, the filtered pond water is enriched with oxygen prior to returning to the pond. Should the local
situation not allow the installation of a water course, extend the outlet using a DN75 pipe for the filtered
water to return to the pond via the pipe. Please refer to the
Installation
chapter for the installation of
a DN75 pipe.
► Horizontal alignment of the FiltoMatic CWS is crucial to prevent drainage of the pond in the event of
an overflow.
Carry out the alignment using a spirit level.
► Take the large volume of the FiltoMatic CWS as well as the resulting weight when filled into account.
Select a suitable ground or a bottom slab in the pit to prevent the FiltoMatic CWS from saggin
g.
►
Plan sufficient space for movement to be able to carry out cleaning and maintenance work.
► Dig a suitably dimensioned pit for the installation of FiltoMatic CWS
(Figure D)

consideration that the FiltoMatic CWS can be buried up to the top reces

with water prior to backfilling the soil to avoid compressing the container.
►
Route the DN40 pipe end for the dirty water outlet at a distance from the pond that prevents the
pumped out dirty water from flowing back into the pond.
